This movab e circular floor is constructedas indicated in Fig. 3, the floor-planking D being nailed to and carriedon wood stringers E E, stren thened and shod by the steel channels F.hese stringto transfer, handle, or store freight or merers are mountedon fixed rollersfG G, and the c'handise' that may be moved or stored onor stringers E E are trussed and across floors of warehouses, wharves,platmeans of the floor-planking D, nailed thereto forms, and decks. andthe truss-rodsH H, put in diagonally at The objects of my invention are,first, to proper intervals.

and useful Improvements in Circular Floor Conveyers, of which thefollowing isa specification.

My invention pertains to conveyers'used be level with a floor, wharf, ordeck, said conveyerto be used for moving and transfer ring freight andmerchandise. without interfering with the use of the floor for truckingor other purposes; third, to provide'a means for receiving, sorting,checking, storing, or 7 lots and ,quantitiesof as herein described andshown freight and merchandise, said means *beinga-ffl a circular floorconve or made to revolve by, any suitable means of operation, and,fourth," to provide a means whereby freight and mer chandise may bereceived, stored, checked, and sorted, transferred, and delivered withless labor, time, and expense than by the present methods of handlingand trucking.

I attain these objects by means of the mechanism illustrated in theaccompanying drawings, in which Figure 1 is a representation of aWarehouse, ship, and barge with my inventionlocated in each. Fig. 2represents a warehouse with my invention located within the same. Fig.13 represents a cross-section of thefioor conveyer, showing itsconstruction and means of operation. Fig. 4 represents a partial plan ofa ship partially equipped with my invention, and Fig. 5 represents across-section of a ship equipped with my invention on The gear J.is'operated and the circular floor thereby turned in either direction,as desired.

v provides a oor conveyer on which freight or merchanship L, or from theship to the car, or from eithership or carto the warehouse, or from thewarehouse to the car or tothe ship. The circular floor conveyer thusforms a means whereby freight and merchandise may be received fromonemeans of transportation and delivered onto a floor or acrosssaidfloor to other means oftran orta'tion. The con"- veyer being'levelwith ti l other purposes.- The conveyer constructed and operated asdescribed and shown will be useful for receiving, storing, sorting, andchecking,'transferring, and delivering freight and nierchandizein largelots or quantities. The work by means of my invention can be done with agreat saving of time, labor, and expense over the present methods of.henting a multiple of conveyers' within or Similar letters refer tosimilar parts in the rises a circular section My nvention com ouse,wharf, platform, or deck so constructed as to be level or flush with thefloor, wharf, platform, or deck and i movable by turning in l a circulardirection.

side. used on the decks of ships and berges, where it may beinstalledand operated as described In using my invention on ships andibarges Ipurpose not only'using a circular floor con- I the entire radius of thecircle on w hich they i filled until all are loaded. By means of theseare constructed, thus forming :1 disk or turret form of floor.

l-purposewhere' desirable to inclose these circular floors with'walls Non the outer circle of the floors and to divide the space inclosed intocompartments by'meens of radial Walls 0. A hatch P is provided in thefloor of one "of the compartments of each u per turret, so the lowerturret ma first be fi ed.

In loading a vessel the lowest turret is first filled, each compnrtmentbein'g filled singly and'the conveyer turned round until all are; full,Whenthe next turret above may be like isc separate compartments thefreight can he loaded in separate lots or shi ments consigned todifferent ports and )e accessible Without disturbing any other portionof the cargo. To accomplish theresult. last men- .tioned, I purposeintro iu'cing side hatches Q in the angles between the turrets.

Doors R, opening into'nny orall of the compartments, give access to eachfrom these nnglcspaces, and any compartment may thus he unloaded withoutdisturhingthc others.

For the shipment ofcocl, ores, grain, send. or gravel the-conipcrtmentsmcntionedmey be constructed with iloors inclined toward thedoors-opening into the side hatches, as indicated at thus causing thecontents to gravitate toward the h utch when the door is opened,fronrwhcrc it can be hoisted, end

'ierehy save the c-xpenseof shoveling that hind of freight. i

The above mentioned and described use of turrets w-ithcom artments inconnection with my circulsr-iioor-convcycrinvention is pplioeble to hipsand barges of one orimorc deck it to he observed the-ti do not uscofcompartments strictly-l ert or v invention but mention the us 1 V i y 1I I r them to show their practical use and application to mynewlyinvented circular floor conve er 1 am aware that prior to myinvention other platform conveyors having straight and circular'movements have been used; but

my conveycr isdesigned to run flush or level with the floor and is maderi 'd and of suflic ient strength to receive an convey heavy loads andin this regard is novel, inasmuch as it differs materially from previousinventions of this character.

Having described my invention, what I claim as new, and desire to secureby' Letters Patent, is

1. A circular fioor conveyer, comprising a .circulnr traveling floor setlevel with a. floor or deck, said floor constructed with stringers andtruss-rods, and said stringers mounted -tp travel on fixed rollers,guide-rollers at the side of the outer stringers and c pinion-gearengaging a. fixed gear on one of said stringers f or turningscidcircular floor conveyer substantially as described and set forth.

2. A circular floor conveyer comprising a circular non-flexible platformlocated and capable of traveling within 9. way on 0p 0- site sides ofwhich, both within and outside of the circle described by the way, is afixed flooring adapted to receive on either side of the platform a loadcarried by the same, substantially as described. 3. A circular floorconveyer comprising a circular non-flexible platform located and capableof traveling within a way on opposite sides of which-both within andoutside of the c1rcle described by'the way is afixcd flooring adapted.to receive on either side of the platform a load carried by the same,suid platform being adapted to, travel in opposite directions asdesired, substantially as set forth.

4. A circular floor conveyor, comprising a. circular platform adapted totravel in opposit-e directions as desired, and composed ofmetal-facedstringers, flooring secured to said stringers-end forming arigid, non-flexible surface to the platform, truss-rods connecting a udbracing the stringers-end fixed rollers suitably located to have saidstringers travel thereon, substantially described.
